How do you understand the process of automation and how does it differ from manual task execution?

Automation is the process of creating systems and scripts that perform tasks without human intervention, replicating or replacing manual operations. Unlike manual execution, automation allows for increased speed, accuracy, and repeatability of processes, reducing the likelihood of errors and saving time.

For example, instead of manually deploying servers and configuring environments, one can write scripts or use tools (such as Ansible, Terraform) that do this automatically according to a predefined scenario.
